Github Icon point to wrong project

[hugosenari]

First, Thank you for setting this up =)

The icon for github project in the site is pointing to CNCF version, that may lead to some confusion for those want to contribute, adding more links.

They don't seem to expose any ways to change this, so we'll have to do this in https://github.com/nixlang-wiki/landscape2 I think

Now I am confused, what we are using? :-D

Fixed in #30
